Unnamed Rhinos

Borg drone []

This Borg drone was discovered "sleeping" aboard a Borg cube by the crew of the USS Protostar. After the Borg were inadvertently awakened by Zero, this Borg approached the Protostar crew, warning them that "Resistance is futile", before eventually assisting in the capture of most of the crew. Later, he grabbed Gwyn when she attempted to free her captured crewmates. He was incapacitated when Zero broke free from the hive mind and disabled a large number of Borg drones with a shockwave. (PRO: "Let Sleeping Borg Lie")

This alien was voiced by Ben Thomas. He was identified in the end credits (and episode's audio description) as a "Rhino Borg".

Tars Lamora miner []

Spike Headed Alien — A recently freed Rhino

This Tars Lamora miner was forced by The Diviner to work for his cause, locating the USS Protostar.

Following their revolt, he assisted a Lurian miner in prying open the hatch to gain access to the engine room of the Rev-12, and proceed to join the attack on Drednok.

After Drednok was decapitated, this alien bragged to another alien on how "I just lowered my head and ka-bam! Did you see that?" (PRO: "A Moral Star, Part 2")

He was later featured in Doctor Jago's advertisement that played aboard the space elevator to Noble Isle in 2384. (LD: "Masquerade")

This alien was voiced by Ben Thomas. He was identified in the end credits as a "Spike Headed Alien".
